Wil Wheaton: Sheldon, I promise that I will work my hardest to make this show great so that a whole new generation of kids will grow up and they will be able to say that Professor Proton was the reason they got into science.

Wil Wheaton: Thanks.
Sheldon: But I won't be seduced by your acting skills nor your movie star charisma. There's only one Professor Proton, and he had neither of those things.
